A high-efficiency advanced vortex separator designed for treating a large flow range while keeping headlosses low. The Downstream Defender removes oil, fine sedimentm, trash and debris from stormwater in a footprint as much as half the size of conventional gravity separators.The Downstream Defender is the most advanced vortex separator ...

A high-rate fluidized bed filtration system that provides sedimentation, screening and filtration all under one lid. Developed with researched funded by the EPA, the Up-Flo Filter is proven to offer high removals of fine sediments, metals and phosphorus with long filter runs at loading rates higher than 10 times conventional surface and radial ...

The First Defense is a cost competitive stormwater pre-treatment device for small urban sites and larger sites where design constraints call for a highly adaptable stormwater treatment device. Surface runoff is piped in or conveyed through an optional surface grate. Peak lows are internally bypassed to eliminate additional bypass manhole ...

A self-activating flow control that uses vortex motion to accurately restrict flows with the largest possible opening. The Reg-U-Flo Vortex Flow Control can be used to minimize storage volumes or ensure efficient use of the system profile.Included in HydroCAD and PondPack software, the advantages of the Reg-U-Flo Vortex Flow Control's unique ...

The Downstream Defender is an advanced hydrodynamic vortex separator for the effective and reliable removal of fine particles along with oils and other floatable debris from surface water runoff.Its innovative design delivers high efficiency across a wide range of flows in a much smaller footprint than conventional or other swirl-type devices and ...
